Looks like I will be taking my truck into a Ford Truck service center tomorrow for warranty work. My metal oil pan is leaking around the seal and looks like it needs to be taken down, cleaned, and put back on with motorcraft sealant. My dilemma is, the service center said they will drain oil and put back in. My OCD is telling me to just give them new oil for oil change. Am I being ridiculous in worrying the oil might get contaminated in their pail before going back in? Current oil is Delvac 5w-40 with like 3,000+ miles on oil...scheduled to be changed February of 2018. Appreciate the advice.
